Anzemet IV Precautions
Before using dolasetron, tell your doctor or pharmacist if you are allergic to it; or to other 5-HT3 blockers (e.g., granisetron, ondansetron); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: heart problems (e.g., irregular heartbeat), stomach/intestinal problems (e.g., recent surgery, ileus, swelling), kidney disease.
Dolasetron may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using dolasetron, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using dolasetron safely.
This drug may make you dizzy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Avoid alcoholic beverages.
To reduce dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.
Caution is advised when using this drug in children with heart problems because they may be more sensitive to the heart effects (e.g., irregular heartbeat) of the drug.
Older adults may be more sensitive to the side effects of this drug, especially irregular heartbeat and QT prolongation (see above).
During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.
